Abstract

Background:  The aim of the present study was to compare the histological characteristics of livers between chronic hepatitis C (CHC) patients with and without hepatitis B virus (HBV) coinfection.

Methods:  A total of 336 CHC patients (male/female: 204/132, mean age: 46.1 ± 11.7 years) were enrolled in the study; 32 patients (9.8%) were positive for hepatitis B surface antigen (HBsAg). The histological characteristics of livers were described according to the Knodell and Scheuer scoring system.

Results:  The proportion of non-intralobular necrosis (score 0) was significantly lower and the mean intralobular necrosis score was higher among CHC patients with HBV coinfection than those without coinfection (43.8% vs 64.5%; 0.84 ± 1.05 vs 0.53 ± 0.89). The epidemiological and virological parameters, and other histological scores (periportal necrosis, portal inflammation, total necroinflammation and fibrosis) were not significantly different between these two groups.

Conclusion:  Chronic hepatitis C patients with HBV coinfection tend to have more severe intralobular necrosis than those with isolated HCV infection.
